I could have sworn that in the "From Hell" event Swen said that if you do the right things, you'd be able to get Us as a camp follower. Maybe they just haven't finished that implementation, or intentionally left it out of EA?
Or maybe my memory is going or they changed their minds...
I just watched this the other day and he said that they stopped short of making it a companion. It went from interactive object to possible encounter to temporary follower.
